A Woman Realized She Was Pregnant After Looking at Her Fitbit Data

David and Ivonne were excited to test out their new Fitbits to get in shape for the new year. But Ivonne's seemed to be on the fritz—until some helpful Internet strangers gave them some incredible news.

Ivonne's data showed that she spent 10 hours in the "fat-burning zone," but wasn't burning a lot of calories and wasn't very active that day. In addition, the numbers showed her heart rate had been high. David posted on a Fitbit forum on Reddit about his predicament, asking fellow users if there was something wrong with her sensor.

But then, a fellow user asked, "Has she experienced anything really stressful in the last few days or is it a possibility she is pregnant?" David instantly knew that was a possibility since they were trying to have kids. Ivonne took a home pregnancy test, and it turns out she was expecting their first child.

David told BuzzFeed that Ivonne is now a month into her pregnancy, so they're keeping their story (and their last names) under wraps for now. A doctor told the website that the elevated heart rate may have been caused by an increase in body temperature, which happens during the early stages of pregnancy. According to the Beth Israel Deaconess Medical Center, a faster-than-normal heart rate usually appears about six weeks into the pregnancy.

"Little did I know I got a lot more than I bargained for," David wrote on Reddit. Now I'm a regular guy who is preparing to have his first child brought into the world, God willing, in October 2016."
